I need your honest Sondy RX100 owners only feedback.What do you love and hate about your camera?

I am a DSLR guy who got used to all the best: fast startup time, great auto focus speed, almost no shutter lag and of course viewfinder.

I bought Fuji X10 last year. Although it is a really good camera, I'm not satisfied with it. Its still big (I can't put it in my jeans back pocket), have fast auto focus speed, but its still far away from what I get used to and it has very inaccurate viewfinder.

I'm highly considering to by Sony RX100 in the last couple of weeks mostly because of its relatively small size. My main concerns are lack of viewfinder - doesn't need, works well even in direct bright sun, auto focus speed - set on center focus, it's as fast as my e-m5, shutter lag and startup time - neither has been an issue for me. What can you say about these?
